Charm sea effects on charmonium decay constants and heavy meson masses

Charm sea effects on charmonium decay constants and heavy meson masses

We estimate the effects on the decay constants of charmonium and on heavy meson masses due to the charm quark in the sea. Our goal is to understand whether for these quantities Nf=2+1 lattice QCD simulations provide results that can be compared with experiments or whether Nf=2+1+1 QCD including the...
